pinyin4.js 汉字转拼音 获取首字母

我记得以前用的 pinyin.js 实现地址省市区的索引列表 是无法区分多音字的。比如：重庆…害的我在 c 的分组里面找了好久都没找的重庆

最近又要写索引列表 于是我才知道这个 pinyin4js.js （github地址）。

npm i pinyin4js

<script>
	import pinyin from 'pinyin4js'
	export default {
		data() {
			return {};
		},
		mounted() {
			console.log(pinyin);
			let a = pinyin.convertToPinyinString("重庆", '#', pinyin.FIRST_LETTER),
			b = pinyin.convertToPinyinString("重庆", '#', pinyin.WITHOUT_TONE),
			c = pinyin.convertToPinyinString("重庆", '#', pinyin.WITH_TONE_MARK),
			d = pinyin.convertToPinyinString("重庆", '#', pinyin.WITH_TONE_NUMBER),
			e = pinyin.convertToSimplifiedChinese("重庆"),
			f = pinyin.convertToTraditionalChinese("重庆");
			console.log(a, b, c, d, e, f);
		},
	}
</script>

打印 pinyin 这个对象，里面有三个方法：

{WITH_TONE_MARK: "WITH_TONE_MARK", WITHOUT_TONE: "WITHOUT_TONE", WITH_TONE_NUMBER: "WITH_TONE_NUMBER", FIRST_LETTER: "FIRST_LETTER", convertToPinyinString: ƒ, …}
FIRST_LETTER: "FIRST_LETTER"
WITHOUT_TONE: "WITHOUT_TONE"
WITH_TONE_MARK: "WITH_TONE_MARK"
WITH_TONE_NUMBER: "WITH_TONE_NUMBER"
convertToPinyinString: ƒ convertToPinyinString(str, separator, format)
convertToSimplifiedChinese: ƒ convertToSimplifiedChinese(str)
convertToTraditionalChinese: ƒ convertToTraditionalChinese(str)
getShortPinyin: ƒ getShortPinyin(str)
__proto__: Object

输出 a b c d e f ：

c#q chong#qing chóng#qìng chong2#qing4 重庆 重慶
